Перевод - Турецкий-Английский - merhaba Sheila. grubum için yeni bir dünya...

...want to perform it. I will be very happy when you send the invitations within today.

yeni not translated
second sentence deviates from original.

Hi serhat,

I've added "within" in front of "today". That's better. Thanks.
But the structure you suggest is not appropriate here.

"I will be very happy" can be used as well. But the current one probably sounds more natural.

Hi kfeto,

Thank you, I've translated "yeni".

Why do you think there is a deviation in the second sentence? In a tour, musicians give performance in the places they visit. So, isn't it clear that they want (the band in the text) to perform at the places mentioned above by organizing tours to these places?

hello Rise
sorry for my late reply
in turkish its clear(bu turneyi) the whole tour is to be held at her bars.
the english as it stands now suggests only one or several are meant to be held at her bars.
if you would add 'it' after perform, sentence would be ok

ps just a suggestion: 'within' is not necessary since that's the only possibility when you write 'today'. 'within a day' is also good

Now I've got the point. Thanks. And thanks for your other suggestion too. I've chosen to omit 'within'.
